They famously became an item after playing on-screen lovers Sookie Stackhouse and Bill Compton in the hit show True Blood.

So hopefully actor Stephen Moyer won't mind seeing his wife Anna Paquin's character move on with other male characters now that Sookie and Bill are no longer romantically entwined.

But in the latest episode of the vampire saga, perhaps Stephen, 43, could be forgiven for wanting to keep a watchful eye on set as his wife filmed her raunchiest scene yet - a naked tryst with new character Macklyn Warlow, played by Rob Kazinsky, 29.

While the show has certainly not been short of nudity over its six seasons, it is the first time new mother Anna, 31, has dared to bare in her first topless scene.

Rob has been setting pulses racing as the half-faerie, half-vampire since the start of the new season, but immediately had his sights set on Sookie.

And the pair certainly have great chemistry as they are seen locked in a passionate embrace, minus their clothes.

It was another opportunity for Anna to show off her impressively toned stomach, less than a year after she gave birth to twins Poppy and Charlie.

In the steamy clinch, Sookie finds Macklyn tied up to a gravestone.

Although the faerie/vampire hybrid warns Sookie he might not be able to control his vampish urges, the pair can't seem to resist each other.

It's not long before Sookie allows Macklyn to feed on her, as they writhe around in the graveyard.

Rob has clearly come a long way from playing Sean Slater in the British soap EastEnders back in 2006.

Speaking about his character's love for Sookie, Rob says: 'He's been waiting six thousand years for her,'

'He didn't know she was going to be a babe. He knew that she was going to be a fairy and a princess and that's all that really mattered to him, because he killed his entire tribe and she is the last of his line.'

But it's not just Sookie that his character has been getting loved up with.

The actor filmed a dream sequence with Sookie's brother Jason Stackhouse, played by Ryan Kwanted, with both getting close in the bathroom.

'That was one of the hardest things I've ever shot in my life,' Rob said, 'solely because we couldn't keep a straight face. Not for one second.'
